Cold Outreach Crashes
When Infrastructure Fails
Most teams lose deliverability before they even send their first email. Weak authentication, cold domains, inconsistent sending limits, and messy DNS signals tank inbox placement before outreach even begins — and you don’t notice until reply rates crash.
Inbox Placement,
Configured From Day One
We set up a complete, delivery-optimised Google Workspace configuration that brings consistency back to your campaigns. SPF, DKIM, and DMARC are aligned, inboxes warm steadily, and domains follow a safe sending rhythm.
With stable inbox placement and clean sender behaviour, your team books more meetings, generates more replies, and grows pipeline without spending extra on domains or broken tools.
How We Set Up Your Google Workspace
for High-Deliverability Outreach
A done-for-you four-step process from mailbox creation to campaign-ready — completed the same day, with full support throughout.
Create Dedicated Google Workspace Mailboxes
We set up genuine Google Workspace Business Starter accounts under your secondary domains — keeping your main brand domain completely safe while giving each campaign its own clean, isolated sending identity. Every mailbox is built specifically for cold email outreach and lead generation.
DNS & Full Authentication Setup
We handle the complete technical configuration for every mailbox. SPF, DKIM, DMARC, and MX records are set up so inbox providers instantly recognise your emails as legitimate and trustworthy. Domains are authenticated to prevent spoofing, improve inbox placement, and protect sender reputation — you don’t need to touch the DNS panel.
Mailbox Warm-up & Sending Optimisation
New inboxes are gradually warmed using controlled sending sequences to build trust with ISPs. US-hosted IPs and sending limits are configured to match cold email best practices. Multi-domain support lets you scale multiple campaigns simultaneously without harming deliverability. Compliance safeguards are applied at every step so your outreach runs predictably.
Connect to Your Cold Email Platform
Once setup and warm-up are complete, your Gmail accounts are integrated with your preferred outreach tool — Instantly.ai, Smartlead, Lemlist, Apollo, Close, or HubSpot — via OAuth (recommended) or SMTP. Your mailboxes are now fully campaign-ready to run scalable cold email sequences that generate replies, book appointments, and grow pipeline.
Cleaner Setup. Safer Sending.
Higher Response Rates.
Here’s what you get with ProspectOut that you don’t get buying Google Workspace directly or through a generic reseller.
All three authentication records are configured and verified from day one. No manual setup, no guesswork, no half-configured DNS that tanks your deliverability on the first send.
At $2.50/mailbox/month, you only pay for the mailboxes you actually use — not bloated enterprise licences. That’s over half the cost of buying directly from Google at $7/mailbox.
All cold outreach runs on secondary domains you provide. Your primary brand domain stays completely protected. If a sending domain ever has an issue, your main business email is untouched.
Most setups are complete within 20 minutes. For larger batches it may take slightly longer, but everything is finished the same day. No waiting days or weeks for configuration to take effect.
We connect your mailboxes via OAuth — not SMTP — for maximum deliverability and tool compatibility. Works natively with Instantly, Smartlead, Apollo, Lemlist, Close, HubSpot, and more.
We support you until every part of your setup works perfectly. Need to add mailboxes, troubleshoot a DNS issue, or reconfigure a sending limit? Priority support is part of the service, not an add-on.

Frequently Asked Questions About
Google Workspace Cold Email Setup
You get fully built Google Workspace Business Starter mailboxes under your secondary domain, configured specifically for cold email outreach. This includes DNS authentication (SPF, DKIM, DMARC), deliverability tuning, inbox warm-up, tracking domain setup if needed, and native OAuth integration with your outreach tool of choice. Setup is included — no extra fees.
Yes. These are essential for cold email inbox placement. We configure all three records correctly so your domain passes authentication checks, which dramatically boosts sender reputation, improves inbox placement, and reduces spam flags. You don’t need to touch DNS settings — we handle everything.
Most accounts are ready within 5–20 minutes. For larger batches it may take a little longer, but everything is completed the same day. Once setup is done, you can plug the mailboxes into your cold email tool and begin sending almost immediately.
Yes. You have full ownership and admin access because the mailboxes live under your own domain. Nothing is rented, shared, or restricted. You control them long-term even if you ever stop working with us.
Yes. These are genuine Google Workspace Business Starter mailboxes created under your secondary domain. No refurbished, educational, legacy, or risk-prone accounts. Real Google Workspace accounts build trust faster, age naturally, and maintain higher deliverability for B2B outreach.

No. This is a simple monthly subscription with no lock-in. Add or remove mailboxes whenever you want depending on your outreach volume. No penalties, no contracts, no minimum term.
Because mailbox creation and Google licensing are instant and tied to your domain, refunds are not possible after setup. However, we support you until every part of your setup works perfectly. If anything isn’t right, we fix it — priority support is included with every setup.
We configure your entire DNS layer correctly so inbox providers immediately trust your mail. SPF, DKIM, and DMARC are aligned. Google IPs stay clean. Sending limits are optimised based on reputation. This combination increases inbox placement, lowers bounce and spam rates, and keeps your domain reputation strong as you scale outreach.
We connect everything through OAuth (recommended for deliverability) or SMTP if your tool requires it. Compatible tools include Instantly.ai, Smartlead, Lemlist, Apollo, Close, HubSpot, and virtually any other cold email or CRM platform. If you’re unsure about your specific tool, just ask — we’ll confirm compatibility before setup.
Yes. Most clients use reply routing so all leads and positive replies land in one central inbox or CRM. This keeps your sales team organised instead of juggling multiple logins across different sending mailboxes. We can help you configure this as part of the setup.
Absolutely. As your lead generation volume grows, you can request additional mailboxes anytime. Scaling horizontally with multiple secondary domains is the safest and most effective way to run high-volume cold outreach without damaging any single domain’s reputation.
